Marrocchesi (U of Siena)\nand the CALET collaboration:\n\nThe CALET Gamma-ray Burst Monitor (CGBM) was operating at the trigger time\nof G275697 (GCN Circ. 20763).  No CGBM on-board trigger occurred at the time\nof the event.  Based on the LIGO localization sky map (bayestar.fits.gz),\nthe part of the northern arc of the high probability area was in the field-of-view of\nCGBM.  The summed LIGO probabilities inside the HXM and the SGM field of view\nare 32% and 70%.\n\nBased on the analysis of the light curve data with 0.125 sec time resolution\nfrom -60 sec to 60 sec from the trigger time, we found no significant excess\naround the trigger time in either the HXM (7-3000 keV) or the SGM (40 keV -28 MeV)\ndata.\n\nThe CALET Calorimeter (CAL) was operating in high energy trigger mode at the\ntrigger time of G275697.  However, no LIGO high probability region was included\nin the CAL's field of view at the time of the trigger.",
